Christians worldwide are celebrating Easter this Sunday, marking the resurrection of Jesus Christ. This year, the joyous day falls on the same date for both Eastern and Western churches.

Christians celebrate Easter to mark the resurrection of Jesus
Christ on the third day after his crucifixion. It is the
culmination of the Holy Week, preceded by Lent, a forty-day
period of fasting.
Easter does not have a fixed date in relation to the civil
calendar. The holiday is celebrated on the first Sunday after the
full moon following the March equinox.

Western Christianity uses the Gregorian calendar to set the date
for Easter, while Eastern Christianity sets the date in accord
with the Julian Calendar. Orthodox Easter and Catholic Easter
fall on the same date this year, though this is not always the
case. The next time this happens will be in 2017.

The Russian Orthodox Church held its largest service by Patriarch
Kirill at the Cathedral of Christ the Savior in Moscow. The
service in the city's landmark cathedral, where over 7,000
worshippers gathered, started at around 11:00 p.m. local time
(19:00 GMT) and lasted for several hours. It was attended by
Russian President Vladimir Putin, Prime Minister Dmitry Medvedev,
and acting Moscow Mayor Sergey Sobyanin.

Shortly before the service, Patriarch Kirill received the Holy
Fire that was delivered directly from the Church of the Holy
Sepulcher in Jerusalem, where the flame miraculously emanates
each year within Jesus Christ's tomb on Holy Saturday. The
Patriarch and worshippers lit candles from the Holy Fire.

"By the long-standing tradition, the Holy Fire has been put
on the candles and lamps in the Cathedral [of Christ the Saviour]
which are later taken to all parts of Russia, to the territory of
entire historical Russia. The holy fire is then lit in thousands
and thousands of churches and homes as a symbol of divine
presence in our life and as a symbol of the invincible
faith," Kirill told the thousands of people who gathered for
the service.

With their candles lit, worshippers led by Kirill walked across
the Cathedral of Christ the Savior. The procession climaxed when
the Patriarch announced “Christ is Risen!” – the
traditional Easter greeting signaling that the holy day has
started. The worshippers welcomed it by all together replying:
"He is Risen Indeed!"

For the 40 days following Easter Sunday, Orthodox Christians will
greet each other with these words.

Prior to the celebration, Patriarch Kirill addressed believers, reminding them that Easter is a
holy day that “celebrates victory over man’s two biggest
enemies – sin and death.”

This year, the Patriarch especially mentioned Ukraine, saying
that the hearts of the followers of the Orthodox Church are
aching for those suffering in the crisis-hit country.

Easter services are also being held at over 36,000 Russian
Orthodox churches across the globe.

Every Orthodox Church in Russia holds Paschal liturgies on the
night of Holy Saturday that last well into Easter morning.

Festive celebrations are preceded by a long period of Lent, which
this year started on March 3. From that date until April 19,
believers abstained from meat, fish, eggs, and dairy products
while spending time in prayer.

Preparations for Easter celebrations begin on the last day of
Holy Week – known in Russia as Passion Week, the strictest week
of Lent. During this week, believers paint eggs (usually red as a
symbol of Christ's blood). They also bake rich Easter cakes with
raisins and nuts. The day before Easter, on Holy Saturday, they
go to church to have their paschal cakes and eggs blessed by
priests.

Easter Sunday is a day for believers to spend with their families
after visiting a church service in the morning. Russia's Easter
traditions include exchanging colored eggs and carrying out the
ritual of cracking them open.

At the Vatican, the heart of the Catholic Church, hundreds of
thousands of worshippers gathered for Easter Mass at St. Peter's
Basilica and the adjacent square. Pope Francis made an Easter
Sunday plea at an altar set up under a canopy on the steps of the
basilica.

The Pope urged for peace and a speedy resolution of ongoing
conflicts, including those in Ukraine and Syria.

He prayed that God would "enlighten and inspire the
initiatives that promote peace in Ukraine, so that all those
involved, with the support of the international community, will
make every effort to prevent violence."

Francis also prayed that all sides in the ongoing Syrian conflict
would move to "boldly negotiating the peace long awaited and
long overdue."

The Pope spoke of Africa, where people are suffering from an
epidemic of deadly Ebola, and urged a halt to "brutal
terrorist attacks" on Christians in parts of Nigeria.

Francis also stressed that people must not forget about the needy
close to home. He said that Easter's joy means "leaving
ourselves behind and encountering others, being close to those
crushed by life's troubles, sharing with the needy, standing at
the side of the sick, elderly and the outcast."
